This summer has brought flooding rainfall to several parts of the U.S. Pennsylvania had its wettest summer on record, and the neighboring states of Maryland, Virginia, and West Virginia each had one of their 10 wettest summers on record. The warming climate enhances the water cycle, leading to more extreme rainfall. The NCEI Climate Extremes Index

Meteorological summer has been one of extremes in the U.S. Overall, the East has been wet while the West has baked in the heat. These types of extremes, which are set up by a consistent jet stream pattern, are amplified by a warming climate. Many locations in the Middle Atlantic, Ohio Valley, and Upper Midwest had one of their 10 wettest summers

In a warming world, a supercharged water cycle ramps up evaporation and precipitation. Warmer air creates higher evaporation rates from the soil, which worsens drought, stresses water supplies, and hampers agriculture. Evaporation of surface waters, such as lakes and oceans, also increases. A warmer atmosphere can hold more water before becoming sa

With flooding in parts of the Mississippi Valley and a strong Pacific storm coming into the Northwest, we examined the trend in the number of days each year with heavy precipitation at 244 individual sites in the U.S. This expands our nationwide-averaged heavy precipitation analysis from earlier this year, complementing the 2017 Climate Science

Californians, say hello to an old friend. After four years of drought, the state’s largest reservoir is again a reservoir instead of a mudpit. Lake Shasta, located in the northern half of the state, was down to just 29 percent of normal storage capacity as recently as December. But one of the strongest El Niño’s on record has helped steer rain to

Spring may officially begin over the weekend, but winter isn’t going down without a fight in the Northeast. Forecasters are watching the development of a storm system that could bring spring snow along a swath from Washington, D.C., up to Boston. As can often be the case with such storms, though, the exact timing of the snow and just where it will

Storms have returned to California, bringing with them much-needed rain and snow after February came up disappointingly dry. But while this influx of moisture is expected to surpass storms earlier this winter, it won’t end the drought and could bring a downside of flooding and mudslides, experts warn. “We will have to see how it plays out to sort

It looks like this El Niño — which will rank among the strongest on record — has passed its peak in terms of tropical ocean temperatures, but it’s not going away anytime soon. In fact, the biggest El Niño impacts on the U.S. are probably still to come. The country has already started to feel the influence of El Niño with a recent spate of storms

Rain, rain, go away. Come again during the next El Niño or record-hot year! Climate Central’s Multimedia Journalism Fellow, Greta Shum, takes us through the past week in weather and climate news and takes a look at 2015 overall on the Shum Show.

After the East Coast just went through its warmest December on record, a shock to the system comes early this week as a brief surge of Arctic chill races in. Meanwhile, El Niño will start to make an impact on southern California. Catch Shift Ahead for this week's weather and climate with Sean Sublette.

It’s like waiting all year for a present that you know is coming, and then being handed an unwrapped box of coal. Central Gulf Coast residents sweat through eight months of the year and yearn for cool temperatures that typically accompany November, December, January and February. However, in this El Niño Autumn, such a chill just hasn’t gotten
